A matte container is a container with the RGB portion of an image on one track and its matte on another. If the matte for a clip exists separately from it, you can add the clip and its matte to the timeline as a single element by creating a matte container for them. You can also create matte containers on import, or from the Tools tab.
To create a matte container on the timeline:
- In the timeline, select the clip you want to add the matte container to.
- In the Timeline FX pipeline, select the proxy for the clip.
Underneath the pipeline, a quick menu appears.
- Click the Add Matte button.
- Select a matte from the workspace. The Matte Container button appears in the Timeline FX pipeline.
If the matte media length is equal to the front length, then the matte segment is positioned at the same start as the front segment. If the matte media length is different to the front length, then the matte segment is positioned at the Container segment start (yellow marks).
- To open the Matte Container, click once on the Matte Container button and then click Open in the quick menu, or double-click on the Matte Container button.
Once the Matte container is open, you can adjust the settings for the matte or add other effects to it.
- If you want to mute the matte, right-click the Matte Container button and select Mute.
- If you want to remove the matte, click once on the Matte Container button and then click on the Uncontain button.
Note: If you use the matte container clip in Batch or Batch FX, the front and matte clips are present in the clip node.
